Sir,
When I connect LM337 with out current boosting transistors, it works fine.
After connecting current boosting transistors and turning on the circuit, the output goes to 30V and ic went to breakdown.
This is same for lm317 section also.
Now problem is with current boost transistor section. Even I cross checked the base , emitter junction of current boosting transistor.
Suggest some solution to built high current bipolar power supply.
Thank you
